What else can I help you with?
Do stars move during the night?
Yes, stars appear to move across the sky at night due to Earth's rotation. This motion is caused by the Earth spinning on its axis, making it seem like the stars are moving when actually it's the Earth moving.
Why do stars shift westward?
Stars appear to shift westward because of the Earth's daily rotation. Also, there is a slower westward movement because of the annual motion of the Earth around the Sun.
What you get when stars are moving away?
When stars are moving away from us, we observe a phenomenon called redshift. This redshift occurs because the light from the stars is stretched, causing its wavelength to become longer. The greater the redshift, the faster the star is moving away from us.
What causes the stars in the sky to appear to be moving?
The Earth's rotation. The relation between the Earth (or a person on the Earth) and the position of the stars makes it appear that the stars are in a different position as the night progresses.
When you face north the sun and the stars appear to move from to?
From your right (East) to your left (West) moving behind you.
If the Earth rotates from the west to the east why do the sun and stars move from the east to the west?
They are not actually, moving, they just appear to be moving because we are. Consider that if you are on a train moving forward, objects that you pass by appear to move toward the read of the train.
If the earth rotates from west to the east why do the sun and the stars move from the east towards the west?
They are not actually, moving, they just appear to be moving because we are. Consider that if you are on a train moving forward, objects that you pass by appear to move toward the read of the train.

What kind of shift do stars have that are moving towards us?
Rotat

Does the medium of space make distance stars appear to be more red shifted only because they are farther away?
Distant stars appear red shifted because they are travelling away from Earth. It just happens that more distant stars are moving faster, so there is a greater red-shift the further a star is from the Earth.
What is blue shift?
Blue shift is a phenomenon whereby a moving object emits light in such a way that the waves of light actually posses a higher frequency than when emitted. Its like a pitcher throwing a fastball versus the same pitcher throwing a fastball from a moving vehicle; to an observer on the side of the road, the ball has a higher velocity when being thrown from the vehicle than from a stationary pitcher. The higher frequency of the light results in a shift towards the blue-end of the visible light spectrum; hence the name blue shift. This is a method used in astronomy to determine that a visible object is moving towards the Earth.
Do stars move from east to west?
Yes, stars appear to move from east to west in the night sky due to the rotation of the Earth on its axis. This causes the stars to appear to rise in the east and set in the west as the Earth rotates from west to east.
Do stars move during the night?
Yes, stars appear to move across the sky at night due to Earth's rotation. This motion is caused by the Earth spinning on its axis, making it seem like the stars are moving when actually it's the Earth moving.
Why do stars appear to move in the sky?
Stars appear to move in the sky due to the rotation of Earth on its axis. As Earth spins, it causes the stars to appear as if they are moving across the sky. This is known as the apparent motion of the stars.
Interstellar reddening is caused by what?
A downward shift in frequency of radiation (perceived as reddening in the visible spectrum) is observed in most stars outside the Milky Way Galaxy. This red shift is assumed to be caused by the stars moving away from our galaxy at a sizable fraction of the speed of light. This shift is similar to the Doppler effect in sound.
Why do stars shift westward?
Stars appear to shift westward because of the Earth's daily rotation. Also, there is a slower westward movement because of the annual motion of the Earth around the Sun.
